GLAUS RUSSMANN, OF HAMBURG, GERMANY.

STEAM BOILER OR GENERATOR.

SPECIFICATION forming part of Letters Patent No. 271,523, dated January 30, 1853.

Application tiled October .9, 1882. (No model.)

To all whom it may concern:

Be it known that I, ULAUS RUSSMANN, of Hamburg, in theEmpir-e of Germany, have invented a new and useful Improvement in Steam Boilers or Generators, of which the following is a specification, reference being bad to the accompanying drawings.

This steam-generator consists ofa n umber of systems of tube-coils arranged one beside another, but placed alternately at different heights. The top and bottom terminal parts of the several tube systems are arranged horizontalorverynearhorizontal,and the terminations partly projectfrom the casinginclosing the coils of the boiler or generator and its furnace, and are at each end connected toavalve-casing of novel construction, hereinafter described, that allows of putting the several systems in communication with each other,or of shutting offsinglesystemsfrom theothersystemsin case the corresponding tube should be damaged, or in case this should be desirable from any other cause. The valve-casings are combined by a tube or channel constructed for regulating the level of water in the boiler, and for the purpose of regulating the pressureof steam. The bottomendsofthetubesdirectlyform thefire-grate, and,although the several systems are arranged close beside each other, the placingof the tubes of alternating systems at somewhat different heights will enable air to pass through the free space so formed between the-different tubes.

The accompanying drawings represent the generator. Figure l is a side elevation, showing the communicating channel between the valve-casings partly in section. Fig. 2 is a front view, showing the communicating channel and bottom valve-casing in section. Fig. 3 is a longitudinal, and Fig. 4 a cross-section, of the generator.

a b c d are different systems of tube-coils placed beside each other, but alternately at different heights, as will be understood with reference to Figs. 1, 2, .3.

H is the valve-casing receiving the top ends of the tubes. H is the valve-casing receiving the bottom ends of the tubes. Sis the fire-door.

The grate is formed by the nearly-horizontal lower terminal portions of the tubes to I) c d inside the boiler-casing.

The upper valve-casing, H, has in it two passages, o and 0, of which the upper, 0, is used for reception of the steam generated, while the lower, 0,is used for blowing through the coils in case the latter have to be cleaned. By vertical as well as horizontal channels each coil is in connection with o as well as 0, while at the same time it can be shut off from 0 and o by cocks i, fitted to the casing H H. The plug-seat and plug of each cock 2' has a central hearing or passage by which it communicates with its corresponding coil, and also two side borings or passages, of which the outer one serves to bring different coils into communication with each other, as these borings terminate in a common channel, on, when the cooks are in a certain positi 11. There are two channels at in each val ve-casing, resulting from the arrangement of the coils of tubes in a double row or alternately at different heights, as before described; but both channels m communicate by upright channels.

The bottom valvecasing, H, has a similar construction to the top one; but the upper channel, 0 serves in this case for introducing the feed-water, while the lower, 0 is outlet when the coils have to be emptied of water or be blown off for the purpose of cleaning. The feed-water passes from the pressure -pump through tube r, some passing into channel 0 and thenceenteringtheditterentcoils,andsome passing upward through a tube or channel, It, and a passage in a casing, D, into a chamber above'a stop-valve, s, that shuts off a passage, 0, communicating with the steam-chamber 0. The feed-water presses this valve 8 down and shuts the passage 0. An escape and safety valve, Z, arranged above valve 8, has for its purpose to let off all water superfluouslyor above the normal pressure forced into D, and also steam from the boiler in case the pressure exceeds the normal to which the valve l is loaded. Such steam escapes from channel 0, through channel 6, valve 8, and valve Z, into the open air, as the passage r is closed by the check-valve of the pump.

P designates a water-gage glass on the tube or channel R, and g'is a cock having a passage constructed to communicate either with the steam-channel e or with the water-channel R, according to the direction in which it isturned. This tap is used as a gage-cock, water or steam respectively making its exit through boring :0.

k k k in the top valve-casing, H, are openings forming outlets for the steam, which openings are as many as required, connected to steampipes, manometer safety valve, 850., while superfluous openings must be closed by screwplugs. One of these openings may be used for reception of a pyrometer in such cases when high-pressure steam is used for heating purposes or for purpose of distillation. The boiler is inclosed in a casing lined with fireproof material. T is opening from the casing for a chimney.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, with tubes at b 0 d, &c, of the valvecnsing H. connected with their upper ends, and provided with the horizontal steam and blow-otf passages 0 0, connected by vertical passages, and the valves or plugs 6, arranged opposite the tubes in said vertical passages, and adapted to be turned to place said tubes in communication with the passage 0 or o, substantially as described.

2. The combination, with the tubes a b 0 (I, &c., of the valve-casing H, connected with their upper ends, and provided with the steampassageo and the passage m, and the plugs or valves i, adapted to be turned to place said tubes in communication with the passage 0 or with each other through the passage m, substantially as described.

3. The combination, with the tubes a b c d, &c., of the valve-casing Ll, connected with their lower. ends, and providedwith the feed and blow-ofl' passages 0 0 connected by vertical passages, and valves or plugs i, arranged opposite the tubes in said vertical passages, and adapted to be turned to place said tubes in communication with the passage 0 or 0 substantially as described.

4. The combination, with the tubes a b c d, &c., of the valve-casing H, connected with their lower ends, and provided with the feed passage 0 and the passage m, and the plugs or valves 1 adapted to be turned to place said tubes in communication with the passage 0 or with each other through the passage at, substantially as described.

5. The combination of the tubes abcd,&c., the valve-casings H B, respectively contain' ing the steam-passage o and the feed-passage 0 the passages or channels 0 and R, communicating with said passages 0 0, the stopvalve 8, adapted to be kept closed by the pressure of the teed-water forced upward through channel R, and the sat'ety-vahe l, allowing the escape of steam as well as of water in case the pressure of one or other exceeds the normal height to which the boiler is to be worked, substantially as herein described.

6. The combination of several systems of coiled tubes arranged beside each other, placed alternately at ditferent heights, and the straight lower terminal portions of the coils serving as fire-grate, substantially as described.
